Certified Android mobile phones

I'm trying to find an answer to something that keeps on appearing everywhere I look, but never has an answer..can anyone help?

The question is this. If I am buying an Android phone with the specific intention of using itb to make Skype enabled video calls, which mobile phones are 'Certified'.

Everywhere I look it says providing the phone is an Android with OS version 2.2 ( for backfacing camera only ) or OS version 2.3 with forwarding facing and backward facing camers ( how would you make a video call without a forward camera I ponder?) I should be ok, although there might be problems if the mobile is not on the 'certified list'...but can i find a copy of this certified list anywhere? No!
